But if my father could stand up to schoolmasters and if he inherited some of his own father's gifts as a teacher, he himself could never have become one. He could teach and loved teaching. He could radiate enthusiasm, but he could never impose discipline. He could never have taught a dull subject to a dull boy, never have said: "Do this because I say so." Enthusiasm spread knowledge sideways, among equals. Discipline forced it downwards from above. My father's relationships were always between equals, however old or young, distinguished or undistinguished the other person. Once, when I was quite little, he came up to the nursery while I was having my lunch. And while he was talking I paused between mouthfuls, resting my hands on the table, knife and fork pointing upwards. "You oughtn't really to sit like that," he said, gently. "Why not?" I asked, surprised. "Well..." He hunted around for a reason he could give. Because it's considered bad manners? Because you mustn't? Because... "Well," he said, looking in the direction my fork was pointing, "Suppose somebody suddenly fell through the ceiling. They might land on your fork and that would be very painful." "I see," I said, though I didn't really. It seemed such an unlikely thing to happen, such a funny reason for holding your knife and fork flat when you were not using them... But funny reason or not, it seems I have remembered it. In the same sort of way I learned about the nesting habits of starlings. I had been given a bird book for Easter (Easter 1934: I still have the book) and with its help I had made my first discovery. "There's a blackbird's nest in the hole under the tiles just outside the drawing-room window," I announced proudly. "I've just seen the blackbird fly in." "I think it's probably really a starling," said my father. "No, it's a blackbird," I said firmly, hating to be wrong, hating being corrected. "Well," said my father, realizing how I felt but at the same time unable to allow an inaccuracy to get away with it, "Perhaps it's a blackbird visiting a starling." A blackbird visiting a starling. Someone falling through the ceiling. He could never bear to be dogmatic, never bring himself to say (in effect): This is so because I say it is, and I am older than you and must know better. How much easier, how much nicer to escape into the world of fantasy in which he felt himself so happily at home.
